RV Investigator ADCP Current Profiles from Tasmanian Landslide Voyage, 2023

Acoustic Doppler Current Profiler (ADCP) data were collected during the RV Investigator voyage IN2023_V02, which investigated a submarine landslide offshore western Tasmania. The voyage took place between March 24, 2023 and April 30, 2023, departing from and returning to Hobart. Data were processed and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling deep-water current patterns based on ADCP measurements from a fixed vessel track.
• Assessing tsunami generation potential based on oceanographic data collected near a submarine landslide site.
• Calibrating acoustic current profiler instruments based on the documented operational parameters and fault investigations.
• Studying temporal oceanographic variability over a five-week period in the Tasman Sea region.

Strengths

• Data collection spanned a specific five-week voyage from March 24 to April 30, 2023.
• Instrument deployment details are specified, including transducer depth of approximately 8.0m below the water line.
• Data were processed using established systems (UHDAS, CODAS) and quality-controlled by CSIRO NCMI IDC.

Limitations

• A portion of the OS75nb data is noted as 'missing or not useful' and was excluded.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
